gh gist edit completion

[hholst80]

I would like to see gh gist edit to support completion from available gists

The current workflow is to run two gh commands: gh gist list and then gh gist edit where the ID needs to be copy-pasted from the first command. If we could run gh gist edit <TAB> and get an inline list of gists to edit (sorted on recent) it would improve the workflow immensely, especially when mouse select and copy workflow is not available.

workaround:

alias gist='gh gist edit $(gh gist list | fzf --reverse | awk "{print \$1}")'
